We have used an efficient first-principles approach in which the Bloch wave functions are projected into maximally localized Wannier functions. Wannier90 tool (implemented within QE) has been used to compute the Wannier interpolated bands, Berry curvature and thereby the anomalous Hall conductivity (AHC) [1]}, [2]}, [3]}, [4]}. The intrinsic AHC is proportional to the Brillouin zone (BZ) summation of the Berry curvature over all occupied states [4]}, [6]}
\(\sigma _{xy} (AHC) = \frac{e^2}{\hbar } \frac{1}{NV_c}\sum _{\textbf {k}\in (BZ)} (-1) \Omega _{xy}(\textbf {k}) f(\textbf {k}),\)
